TODO

An incomplete list of known issues and desired featues.

TX and RX amounts on UI are wrong for a few frames at startup because we subtract (total sent - 0). We should initialize sent bytes before displaying.
Rewrite common/dbc.py to be faster and cleaner, potentially in C++.
Add module and class level documentation where appropriate.
Fix lock file cleanup so there isn't always 1 pending upload when the vehicle shuts off.
